```swift
var kDNSServiceProperty_DaemonVersion: String { get }
```

## Discussion

Discussion When requesting kDNSServiceProperty_DaemonVersion, the result pointer must point to a 32-bit unsigned integer, and the size parameter must be set to sizeof(uint32_t). On return, the 32-bit unsigned integer contains the version number, formatted as follows: Major part of the build number * 10000 + minor part of the build number * 100 For example, OS X 10.4.9 has mDNSResponder-108.4, which would be represented as version 1080400. This allows applications to do simple greater-than and less-than comparisons: e.g. an application that requires at least mDNSResponder-108.4 can check:      if (version >= 1080400) ...   Example usage:      uint32_t version;  uint32_t size = sizeof(version);  DNSServiceErrorType err = DNSServiceGetProperty(kDNSServiceProperty_DaemonVersion, &version, &size);  if (!err) printf("Bonjour version is %d.%d\n", version / 10000, version / 100 % 100);
